Abstract In this work, the effects of liquid polarity on the intrapolymer diffusion rates of iso‐Butene, using the heterogeneously catalysed hydration of i‐Butene to tert‐Butyl alcohol, are studied. Values for the effective diffusivity are correlated as a function of tert‐Butanol concentration and temperature. The tortuosity factor of the solid polymer matrix is seen to decrease with temperature and increase with alcohol content. Tentative conclusions regarding the shrinkage of the macroporous matrix, are drawn.
